STRAP-CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent'No. 639,272, dated December 19, 1899.

Application filed October 4, 1899.

To all who/1t it may concern:

Be it known that I, CHARLES W. NEWTON, a citizen of the United States, residing at Marlborough, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Strap-Cutting Machines, of which the following is a speci iication.

This invention has for its object to cut off io pieces of strap, the length being regulated by the machine, from narrow strips which are fed into the machine. These straps are preferably, but not necessarily, fabric or webloing; and thc principal object of the contriv- `I5 ance is to cut off pieces from this webbing of suitable length to be used for shoe-strapsthat is, straps or loops applied to boots or Shoes and used as aids in drawing them onto the foot.

In this machine one or more tapes or Straps are unwound from a corresponding number of spools or bobbins and conducted by feedrolls between a pair oi' open jaws until the desired length of strap or tape extends beyond said jaws. The jaws then close upon the tape, and a rotating knife advances and cuts oif the length which extends beyond the jaws. The jaws then open to allow of anotherlength of tape to be fed into and through 3o them.

The nature of the invention is fully described in detail below, and illustrated in the acccompanying drawings, in which- Figure l is a plan view of the machine, a

portion of the housing of the knife being Shown in horizontal section. Fig. 2 is a front elevation of the same. Fig. 3 is a detaill in plan showing the position of the parts when the tape or strap is being cut off. Fig. et is a 4o section taken on line 4, Fig. 1.

Similar letters of reference indicate corresponding parts.

A represents a suitable table or frame formed up into the raised bed A and supported by legs a.

b is the driving-pulley, fast on the drivingshaft B, mounted in the frame C, which is formed with a standard O, pivotally secured to the table A at c, Fig, l, and Swings hori- 5o zontally thereon, being guided and limited in such swinging movement by the screw d,

seria No. 732,463. (No modali which extends through the slot d in the horizontal arm C of the Swinging frame to the ta ble A. This swinging frame O is formed with a curved extension O, and the driving-shaft is mounted on the extension O and standard O.r

The shaft B is belted by means of the fast pulley e to the pulley e', loose on the shaft D, supported in the frame, and a pulley e, integral with the pulley e', is belted to thelpulley e, fast on the Shaft D, one end of which is supported directly by the frame and the other end is sustained by a bracket f, extending downward from the under side of the table A. Rigid on this shaft is the cam D.

The inner end of the shaft B has mounted on it a cutter E, which is protected by a housing E of substantially the shape shown. The table A is provided with an opening or Slot A", through which an arm H extends from the swinging frame O, said arm being held normally against the shaft D in the path of the cam D by a spring g, whose opposite ends are secured to said arm and to a hook g', Fig. 4, secured to the under side of the table. By this means both the arm and the frame O are held swung normally back.

I is a stationary jaw extending vertically from the base I', secured to the bed A, and l is a guide extending vertically from the base I, secured to the bed A', said guide being opposite a vertical spring-guide J, secured to the front edge of the housing E.

K is a movable jaw extending vertically from the sliding base K and pivoted at K to the bed A' opposite the stationary jaw I. A pin L extends up from the jaw K through a slot N in the engaging plate N, secured to the portion O of the frame O, and a spring Zhas its oppositeends attached to said pin and to a standard Z, extending up from the base I.

Mounted on the shaft D is the beveled gearwheel P, which engages with the pinion P on 4the vertical stud or shaft O, which has mounted on it a gear-wheel P", engaging a gear-wheel R on the stud or shaft R. The vertical shafts O and R are Supported by the bed and have mounted on their upper ends above said bed the feed-wheels S and T, respectively.

One end of the Shaft D is provided with a IOO VK being open or apart.

crank D, Fig. et, whose outer end is connected by the crank-arm U with the arm U', loose on the shaft D, said arm being provided with a pawl U", adapted-to engage the ratchetwheel V, fast on said shaft D.

A suitable box W, preferably divided into compartments by partition IV', has in each compartment a roll of tape Y to be fed into the machine and cut into strips. One or more, preferably two or more, ends from the rolls are fed around the guide t and in between the feed-rolls S and T, the jaws I and Power being applied to the machine, the shaft D is operated, by means of the pulleys c, e, e, and e and their connections, with the effect that the crank D'" through the crank-arm U and pawl U im arts a iartial rotation to the ratehet' wheel V, which, through the shaft D, imparts a similar rotation to the gear-wheel P, thus rotating the feed-rolls S 'l by means of intermediate gear ILP", and R. By this means the tapes are fed by the rolls between the jaws I K and through them between the guidingplates I and J. This feeding process continues until the crank D" has swung under and rearward and has commenced to swing upward from the level of thelshaft D. .Iust before the crank has reached this point the cam D has swung up and forward and has commenced to bear against the arm II. As the rotation of the shaft D continues the cam presses the arm H forward and of course lswings the frame O forward, allowing the spring Z to draw forward and close the jaw K against the tapes, which are between it and the stationary jaw I. The same forward movement of the frame C causes the knife, which is rotating with the shaft B, to move between the outer ends of the jaws I K and the inner ends of the guiding-plates I" .I and cut off the tapes. Further operation of the machine of course duplicates the above-de scribed process.

In order to regulate the lengths of tape cut off, I apply to the ratchet the weil-known shield X, whose arm X is engaged in suitable openings in the plate X, secured to the frame of the machine, the contrivance being too common to require further explanation.

A spring adjustment Z preferably holds the feed-roll T against the feed-roll S. Thus any reasonable number of tapes may be fed into and through the jaws and suitable lengths out therefrom with economy and accuracy.

IIaving thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-' l.
